What is the value of a 1934 over under engraved superposed 12 g with an add 20 g over under barrel?

There are many determining factors that will account for the value of your browning superposed shotgun.These fine pre world war II shotguns had a lot of options available to them.If we are looking at the basic model superposed shotgun then the value of thse fine guns run between 1,000 dollars for a gun with 60% original finish on the wood and metal,up to 2,200 dollars for a fine example with 95% original finish remaining.The extra barrel set would bring 35-50% extra to the above stated values if they were in the same gauge.I do not know the value because they are in 20ga.and how that would effect the price.There was also the pigeon grade which is valued at 1,900-6,750 dollars for the same above stated range in finish(60%-95%)If you have a diana grade then the value would be 2,750-6,750 dollars.If you have the midas grade then the values would be 3,000-8,500 dollars.You may want to identify your superposed by going to the browning web site and looking at the customer service section for help in identifying your make and grade of superposed.The serial number would be the most important factor in identification.good luck
